CONDUIT ELECTRIC RAILWAY.

SPECIFICATION forming part of Letters Patent No. 541,020, dated June 11,1895.

Applicationfiled'September 16,1894. Serial No. 522| (N nfide T0 aZZ whomit may concern.- Be it known that I, DANIEL W. SMITH, of

the city of St. Louis, State of Missouri, have invented certain new anduseful -Improve' ments in Conduit Electric Railways, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming a part hereof.

My invention relates to a conduit for electric railways, the object ofmy invention beingto construct a cheap and simple conduit,

simple and efiicient means ofpositioning the conductor or conductorswithin said conduit, and the construction and positioning of a guard forthe conductor or conductors.

A further object of myinvention is'to form a simple (and efficientcrossing for the conductors in conduits without necessitating thecutting or splicing of said conductors.

My invention consists in certain novel features of construction,combination and arrangement of parts, hereinafter described anddesignated in the claims.

Referring to the drawings, Figure 1 is a cross-sectional view of aconduit, showing a single conductor positioned therein. Fig. 2 is across-sectional view of a conduit, showing a pair of conductorspositioned therein. Fig. 3 is a perspective view of a loop 1 form in theconductor and make use of at the crossings of the conduits andconductors. Fig. 4 is an elevation of the loop, showing the secondconductor passing through said loop and a trolley in engagement withsaid second conductor and passing through the loop. Fig. 5 is a View inperspective, showing the loop in use in the overhead system ofconductors. Fig. 6 is a side elevation of one of the conductor clamps orhangers of which I make use in carrying out my invention. Fig. 7 is across-sectional view of one of these hangers and the support for same.

Referring by numerals to the accompanying drawings, 1 indicates theconduit which is preferably tubular in form and provided with upwardlyextending portions 2 and outturned flanges 3. Thus the slot 4. is formedbetween the vertical portions 2. This conduit is adapted to be locatedin the ground as is ordinarily the practice.

Extending through the conduit to one side of the center is the conductor5,. the same being sustained or held at various points in the conduit bymeans of either vertical or horizontal hangers 6, provided with theplates 7 which are rigidly fixed to the interior of the conduit in anysuitable manner, and the com ductor-clamps 8. These clamps 8 comprisethe body portion 9, flat top surface 10 and tapered ends 11. In thecenter of the top flat surface 10 is a raised portion 12 on both sidesof which and on the opposite sides of the body portion 9 are books 13.

The conductor 5 is adapted to lie upon the fiat surface 10, passesbeneath the right and left hand hooks 13 between which it willnecessarily be raised and thrown out of a horizontal line by reason ofthe raised portion 12.

The hanger 6 is rigidly secured to the body portion 9 on one side of theclamp. When the crossing in the conduit is reached, the conductor 5 isgiven a vertical bend 14, then a horizontal bond 15 aL right angles tothe main conductor 5, and is now bent into a loop 16, the same beingpreferably circular. The conductor is now given a horizontal bend 17 tocorrespond with the bond 15, a vertical bend 18 to correspond with thevertical bend 14, and from thence in a horizontal line on through theconduit. This, as it will be seen, forms a loop, through the top portionof which is a passage 19. The conductor 20 passing at right angles tothe conductor 5 is passed through the loop 16 at one side of the centerof the same and held in position by hangers, such as 6. Thus it will beseen how the trolleys of the respective lines will pass along on theconductors 5 and 20 and not interfere in any waywith each other.

The trolley carrying the trolley-wheel that runs on the conductor 20willpass through the passage 19, while the trolley-wheel running on theconductor 5 will pass along said conductor and being of suitable sizewill contact with the vertically bent portion 18 before it leaves thevertically bent portion 14.

Afterthe conductors have been hung within the conduits, suitable guards21 are firmly secured to the interior of the conduit and depend in sucha manner as that their lower edges will terminate slightly below theconductor or conductors 5. These guards 21 are preferably ofnon-conducting material and are for the purpose of preventing anythingfrom coming in contact with the conductors after having been introducedthrough the slot 4.

Thus itwill be seen howI have constructed a simple, inexpensive andcomplete conduit for electric railways, and one that is easily cleanedand kept in order.

\Vhat I claim is i 1. In a conduit electric railway,aloop formedintegral with and in the length of the condoctor at the crossings of theconduit, said loop comprising the vertically bent portions 14; and 18,horizontally bent portions 15 and 17 and the circular loop 16, all bentfrom the length of the conductor 5.

2. In a conduit electric railway, a suitable hanger as 6, in combinationwith a clamp 8 comprising a body-portion 9, the same being provided withtapered ends 11, a flat upper surface 10, a raised curved portion 12 atacentral point in the length of the clamp, and right and left hand hooks13 on each side of said raised portion and projecting in a plane abovethe latter, for the purpose of engaging the conductor.

In testimony whereof I aflix my signature in presence of two witnesses.
